BitmapData Resolution from Webcam

Is there a way, using AS2, to increase the resolution of BitmapData drawn from a webcam video to a value greater than 160x120? The video resolution is set at 768x1360 so in addition to the BmD not being the desired size, it is also forced to 4:3 aspect ratio. I’ve searched extensively for an answer and can’t seem to come up with one. Any suggestions?
